Application filed August 7', 190s. serial No. 447,379.

To all whom 'it may concern: f

Be it known that I, GEORGE GoETz, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Automatic Weighing andRecording Mining-Car Scales, of which the following is a specication.

My invention relates to scales -for automatically weighing .and printingor recording the weights of cars as they pass underI continuous motionover the scale plat-form.

The object of my invention is to provide a weighing'and recording carscale of a simple, efiicient and durable construction by means of whichcars may be accurately. weighed and the weights thereof recorded 'withinlimits of a few pounds as the cary counterbalance spring connected withthe scale beam below the same, and a printing wheel above whe scale beamand connected therewith, s that the connection between the scale beamand the count-erbalance spring and'v printing Wheel may be short anddirect, and thus enable the car while under motion to be .accuratelyweighed `and. its

weight recorded -within limits of a` few pounds. f l

It further consists, in, connection with these parts, of a track leveron the scale platform, fulcrumedy to swing in a plane parallel with thetrack rails so that any variation lof distance of the car wheel ang'efrom the track rail will not materially or detrimentallyv affect theoperation of the track lever.

It further consists' in connection with these parts, of a scaleplatform'furnished with-inclined track rail seats so that the cars maydrop or run over the scale platform by gravlty without the necessity ofany tractive force being applied thereto.

It further consists in the novel construction of parts and devices, andin the novel combinations of parts and devices herein shown anddescribed and more particularly specified in the claims.

Figure l is a plan view of an automatic weighing and recording miningcar scale embodying Jmy invention; Fig. 2 is a side elevation; Fig. 3,an enlarged section on line 3 3 of Fig. 1; Fig. 4, a det-ail section online 4 4 of Fig. 1; Fig. 5, .a detail section on line 5 5 of Fig. 4;Fig. 6, a partial plan View showing the case in horizontal section; Fig.7, a detail Section on line 7 7 of Fig. 6; Fig. 8, a detail elevation ofcertain parts shown in Fig. 7; Fig. 9, a partial plan view of the typewheel and other parts;

' In the drawing, A represents the platform ,of a car scale, B the scalebeam, C the coun- "terbalance spring, D the type or printing wheel, Ethe stationary indcatortype, `F

f Wheels of the mining car Y and N the track lever setting andconnecting mechanism through which the printing hammer is automaticallyraised and released and the paper` strip feed roller automaticallyturned and released, and the ink ribbon feed mechanism automaticallyactuated through the agency of the track lever M.

The scale platform A is preferably an iron or metallic casting, andfurnished with seats a for the track rails A1 which connect with thetrack rails A2 of the railway track at each end of the scale platform.The track rail seats a; are preferably higher at the entrance end thanat the exit end so that the mining car Y may drop or run by gravity overthe scale platform, the grade of the stationary track rails A2 on eachside of the scale platform and of the track rails A1 on he scaleplatform due to the raised rail seats a at the entrance end of the scaleplatform being preferably about av siXtenths per cent. grade; so thatthe mining car Y will drop or run by gravity over the scale platform andthus enable the car to be more accurately weighed while in motion, as itis thus freed from all traction errors orinfluences.

The scale platform A is furnished with wood or other cushionin orsomewhat elastic supporting bars A3 beneath thesame, which are supportedpreferably upon steel I beams A4; so that these cushioning bars A3 mayneutralize or compensate l:for any sudden jars or shocks that might beotherwise communicated to the scale platform by the sudden passage ofthe mining car Y onto,

over and off the same, and thus eliminatev sources of error in weighingand recording the weight which would be due to a more rigid constructionof scale platform.

The scale beam B is provided with counterbalance weights B1 for use inbalancing thescaleand is connected with the customary scale levers A*5beneath the scale platform A, and upon which it is supported and bywhich scale levers the scale platform is connected with the scale beam Bthrough suitable connecting links B2 and connecting levers B3. The scaleplatform is further provided with an extension B* at .its end,

4 through which it is connected with the counterbalance spring C belowthe scale beam, the type wheel D above the scale beam and dash-pot Ilbelow the scale beam, the type wheel and recording mechanism beingarranged above the scale beam so that all the necessary connectionsbetween the scale beam and the countrbalance spring, dash-pot and 4typeWheel may be as simple, short and direct as possible, and thus eliminateas far as may be all source of friction or binding between differentparts of the mechanism and inaccuracies r errors in weighing andrecording the weights incident thereto, and also so that any lateralvibrations of -the scale beam or of the upright framework supover thescale beam platform may be eliminated as sources of error as far aspossible.

The counterbalance spring C is connected with the scale beam B throughsuitable connecting links or clevices b and the counterbalance spring isfurnished with suitable tension adjusting devices C1 C2.

The type wheel D has a metallic rim d, a type rim d1 furnished withnumeral type cl2, a double rimmed hub d3, each having lateral flanges d4to receive the threaded and with screw threads il and nuts d'. Thedouble rimmed hub d3 of the type Wheel is secured to a rotatable shaftals, which is fur' nished at each end with bearingspindles d. The typewheel spindles i9 are very much reduced in diameter in respect to theshaft d8. The spindles of the type Wheel shaft are journaled orsupported at each end upon a pair of large anti-friction wheels orrollers el, the shaft Z13 of each of which is in turn journaled upon apair of anti-friction wheels or rollers d, the shafts d of which arejournaled on the standards D1 on the frame D2 of the weight recordingmechanism. By this construction and ournaling of the type wheel, I amenabled to make it very strong and rigid and accurately true in shape,and at the same time, verylight in Weight and to reduce its inertia asfar as possible, and also the friction of its turning to a minimum, sothat no appreciable inaccuracy in weighing or in recording thc weightcan result from ineflicient action of the type Wheel ^under influence ofthe scale beam and its counterbalance spring. The type Wheel shaft da isfurnished with a spur gear d, which meshes with the rack b3, which isadjustably connected by the connecting rodb* able connections b5 b, Thetype wheel shaft de -is further provided with a spirally grooved pulleyd", carrying a cord or line dla and a counterbalance weight dlg, whichcounterbalances or neutralizes the force required to turn thetype wheel,and serves sensitive and accurate action of the type wheel in respondingto the weight of the car being weighed.

The stationary indicator type E preferably consists of a narrow orindicator mark, and is mounted on the stationary recording mechanismframe D2 adjacent to the type wheel D at one side thereof and direct-lyover its shaft, so that the printing hammer G will cause a simultaneousimpression to be porting it, incident to the passage of the car.

adjustable spokes d5, Which'are furnishedwith the scale beam B throughthe adjustalso to take up back lash and insures a more y or ribbon Xupon which the weight of the mining car Y is automatically printed orrecorded, as it passes continuously over the scale platform vB,preferably consists in' a feed roller which is automatically turned asrequired by a suitable spring or other motorL to cause the paper stripto be fed along the required space as each car passes over the scaleplatform. The paper strip X is thus fed from the reel or spool F1 to thetake up spool F2, the paper strip passingover or around the severalguide spools or rollers f f1 and f2 and over and across the type wheel Dand stationary indicator type E y and under the inking ribbon K. v Thepaper strip feed motor F3 whichactuates the paper stripl feed device Fmay be a springv motor, and is preferably arranged to act upon the feedroller F through the paper strip X itself, the motor F3 thus keeping thepaper strip X normally under tension so that the moment the notched diskf3 on the shaft f4 is released by its spring pawl lever f5 and pawl f3,ythe paper st-rip or ribbon may be automatically fed forward therequired distance. The guide roller f2 for the paper strip X is mountedupon a movable arm or ,lever f7 which is held against 'the paper feedroller F under the required tension by means of a spring fg'on the stemf", the tension ofthe spring being regulated' through the adjustingscrew f1". The releasing pawl lever f5 for the paper strip feed roller Fis automatically actuated from the track lever M at the entrance end ofthe scale platform` as the last wheelV y of the mining car passes ofilof the scale platform through Y suitable connecting mechanismhereinafter to be described. The ratchet shaft f4 is connected by spurgears f j12 with theshaft'f13 of the paper feed roller f1'. The ratchetshaftf3 preferably has a ratchet f1* and a pawl j which is operatedthrough 'suitable connect-ing mechanism from the track lever hl topositively turn the paper strip feed roller F automatically. y

The paper strip feed motor F3 is a spring `motor 'and comprises a springf1, winding shaft f1? therefor, having crank f13 and a train ofintermeshing gears f19 fzo' f3 f33, the'latter on the governor shaftf23, and

gears f2 and f21 being on the shaft f of the takeup spoolF2. Thegovernor preferably comprises astationary friction rim' f2? againstwhich the sliding blocks f2" on the governor arlnf3"t ride, a spring f2sforcing, the blocks f3? otward.` The winding shaft f is provided with aratchetA P3 engaged by a pawl f3.

'The printing hammerG is carriedby alever G1 having an arm G2 furnishedwith a spring G3 which actuates the printin hams mer to strike therequired blow the instant .the printing hammer lever is released by thetrack lever operated trigger or pawl, g which engages the pawl end G4 oftheprinting hammer lever and holds the printing hammer lin its raisedposition ready to krint the weight of the car.v The printing ammer isautomatically raised into position for printing by the track lever M atthe exit end of the scale platform as the rear wheel of the mining car'Ypasses olf the scale platform thlrough suitable connecting mechanismhereinafter to be described. .The printing hammer releasing trigger orpawl g which holds the printing hammer in its raised po` sition'isfurnished` with a spring g1 to hold it in engagement with the notchedend of the printing hammer lever G1, and this trigger or pawl lever g isautomatically actuated to releasethe printing hammer-by the track leverM at the e'Xitend of the scale platform B as the front wheel of themining car Y passes over said track'lever'M. and before such front wheelof the mining car passes ofi` of the scale platform, this being donethrough suitable connecting mechanism hereinafter to be described.

' The piston H1 of the dash-pot H isA oon- .nected with the vscale beamB through its stem h. And this piston 'H1 is furnished with a pluralityof upwardly opening valves'` h1 and a plurality of downwardly openingvalves h2, each of said' valves being fur-c nished with a plurality ofYlight flat springs k3 h3 h5, each of said springs having a separate. andindependent adjusting device or screw h6 for regulating the tensionthereof and the three springs for each valve be1ng\10 (if/graduatedstrength or tension; so that-the dashpot piston may act very Vquicklyand with great precision and steadiness of movement under influence ofthe scale beam B :the printing hammer G descends, it will p cause adistinct impression to be made upon the paper strip X. The inking ribbonK is automatically fed or moved as required by the track lever M as thelast wheel of the car passes over the same through suitable connectingmechanism hereinafter to'be derscribed, and which actuates a pawl leverK7 carrying a pawl K8 which engages 'a ratchet K9 of the take up ribbonspool K1.- The shaft ofV the ribbon spool K1 is furnished with anindicator disk- K11 to show that the inking ribbon feed mechanismproperly opv crates. y
